Definitions
- This invention relates to articulated trailers for the transport of freight containers.
- the invention is particularly concerned with an articulated trailer for the transport of freight containers of the type comprising an elongate wheeled chassis having a kingpin adjacent a front end of the chassis for engagement with a fifth wheel coupling on a tractor vehicle, a top of the chassis defining a bed for reception of a container with a plurality of twist-locks mounted on the chassis, said twist-locks having locking bolts which are releasably engagable with a complementary set of receivers on a container to secure the container on the trailer bed.
- pairs of twist-locks are provided at a front end and at a rear end of the chassis for engagement and locking with associated receiver blocks on the bottom of the container box to rigidly secure the container box on the trailer chassis for transport.
- Container boxes are widely used for world-wide transport of goods. A problem can arise for transport companies in that standard U.S. and European container boxes have a number of differences to meet different regulatory requirements. For example, a standard European intermodal container box has a 13.6m length whilst a comparable standard U.S. container box has a 45ft (13.716m) length. The centre distance between the forward and rear twist-lock receivers is the same for both types of container box so . both types of container can be mounted on conventional trailers in the U.S. or Europe as required as the spacing between the twist-lock mounts on the trailers is the same. However, the positions of the twist-lock receivers on U.S. and European container boxes is not the same. In a U.S.
- the distance from the front end of the box to the front twist-lock receiver is the same as the distance between the rear twist-lock receiver and a rear end of the box (this distance being about 865mm for the 45ft box).
- the comparable 13.6m European box has a 900mm distance between the front end of the box and the front twist-lock receivers and a 714mm distance between the rear twist-lock receivers and the rear end of the box.
- European regulations require a maximum distance of 12m between the centre line/pivot axis of the kingpin and the rear end of the container box when it is loaded on the chassis.
- a single chassis configuration (in particular the relative positioning of the twist-locks and kingpin) cannot accommodate both types of container box and still meet European regulations.
- trailers have to be provided for handling different boxes which provides added expense and inconvenience to transport companies.
- some trailers have been provided with an adjustable kingpin which can be mounted in two different locations on the chassis, the location chosen depending on the type of container box to be carried.
- moving the kingpin between the two locations is a cumbersome, time consuming, messy and generally inconvenient task and therefore this is not generally regarded as a satisfactory solution and is not widely used.
- the present invention is directed towards overcoming this problem.
- the invention is characterised in that a fixed kingpin is mounted on the chassis and two sets of twist-locks are provided on the chassis, namely a first twist-lock set associated with carriage of a European standard 13.6m container box and a second twist-lock set associated with carriage of a U.S. standard 45ft container.
- the relevant positions of each set of twist-locks and the kingpin on the chassis are such that when each type of container box is mounted on the chassis engaged with its associated twist-lock set it will meet the statutory regulations.
- each set of twist-locks is positioned on the chassis such that upon engagement with the associated container the radius between a pivot axis of the kingpin and a front corner of the container is 2040mm.
- each dual twist-lock assembly includes two juxtaposed twist-locks, namely a front twist-lock associated with the U.S. container and a rear twist-lock associated with the European container, a complementary pair of rear twist-locks associated with each pair of twist-locks in the front dual twist-lock assemblies being mounted at a rear end of the trailer.
- each front dual twist-lock assembly has axes which are longitudinally spaced-apart on the chassis by a distance of about 151mm and the longitudinal distance between the rear twist-lock bolt axis and a rotational axis of the kingpin is about 700mm.
- a pair of dual twist-lock assemblies are mounted at a rear end of the trailer, each rear dual twist-lock assembly having a front twist-lock associated with the U.S. container and a rear twist-lock associated with the European container.
- the longitudinal distance between the front twist-locks of the front dual twist-lock assembly at the front end of the trailer and the front twist-locks of the rear dual twist-lock assembly at a rear end of the trailer is 11986mm.
- a single pair of rear twist-locks are provided at a rear end of the trailer, the spacing between the twist-locks in the dual twist-lock assemblies at the front end of the trailer and the associated rear twist-locks being adjustable.
- the trailer is a two-part telescopically adjustable trailer having a front part slidably mounted on a wheeled rear part, the dual twist-lock assemblies being fixed at a front end of the front trailer part and the rear twist-locks being fixed at a rear end of the rear trailer part.
- the trailer is a two part telescopically extendable trailer
- two different pairs of front twist-locks are provided on the front trailer part whilst only a single pair of twist-locks is required on the rear trailer part which can be slidably adjustable relative to the front trailer part to position the rear twist-lock pair as required for use with either type of container box.
- the invention provides a twist-lock assembly for a trailer for freight containers, the twist-lock assembly comprising two juxtaposed twist-locks, each twist-lock including a container receiving platform and a locking bolt for releasable locking engagement with a complementary receiver on a container, said locking bolt being movable relative to the platform between a raised in-use position extending above the platform and a lowered inoperative position below a container receiving surface of the platform, longitudinal axes of the bolts being spaced-apart by a distance of about 151mm.

Abstract
Description
- This invention relates to articulated trailers for the transport of freight containers.
- The invention is particularly concerned with an articulated trailer for the transport of freight containers of the type comprising an elongate wheeled chassis having a kingpin adjacent a front end of the chassis for engagement with a fifth wheel coupling on a tractor vehicle, a top of the chassis defining a bed for reception of a container with a plurality of twist-locks mounted on the chassis, said twist-locks having locking bolts which are releasably engagable with a complementary set of receivers on a container to secure the container on the trailer bed. Typically, pairs of twist-locks are provided at a front end and at a rear end of the chassis for engagement and locking with associated receiver blocks on the bottom of the container box to rigidly secure the container box on the trailer chassis for transport.
- Container boxes are widely used for world-wide transport of goods. A problem can arise for transport companies in that standard U.S. and European container boxes have a number of differences to meet different regulatory requirements. For example, a standard European intermodal container box has a 13.6m length whilst a comparable standard U.S. container box has a 45ft (13.716m) length. The centre distance between the forward and rear twist-lock receivers is the same for both types of container box so . both types of container can be mounted on conventional trailers in the U.S. or Europe as required as the spacing between the twist-lock mounts on the trailers is the same. However, the positions of the twist-lock receivers on U.S. and European container boxes is not the same. In a U.S. container box the distance from the front end of the box to the front twist-lock receiver is the same as the distance between the rear twist-lock receiver and a rear end of the box (this distance being about 865mm for the 45ft box). The comparable 13.6m European box has a 900mm distance between the front end of the box and the front twist-lock receivers and a 714mm distance between the rear twist-lock receivers and the rear end of the box. European regulations require a maximum distance of 12m between the centre line/pivot axis of the kingpin and the rear end of the container box when it is loaded on the chassis. A single chassis configuration (in particular the relative positioning of the twist-locks and kingpin) cannot accommodate both types of container box and still meet European regulations. Therefore, generally separate trailers have to be provided for handling different boxes which provides added expense and inconvenience to transport companies. To overcome this problem some trailers have been provided with an adjustable kingpin which can be mounted in two different locations on the chassis, the location chosen depending on the type of container box to be carried. However, moving the kingpin between the two locations is a cumbersome, time consuming, messy and generally inconvenient task and therefore this is not generally regarded as a satisfactory solution and is not widely used.
- The present invention is directed towards overcoming this problem.
- The invention is characterised in that a fixed kingpin is mounted on the chassis and two sets of twist-locks are provided on the chassis, namely a first twist-lock set associated with carriage of a European standard 13.6m container box and a second twist-lock set associated with carriage of a U.S. standard 45ft container. The relevant positions of each set of twist-locks and the kingpin on the chassis are such that when each type of container box is mounted on the chassis engaged with its associated twist-lock set it will meet the statutory regulations.
- It will be appreciated that from the road haulier's point of view and the tractor driver's point of view this is a very neat and simple solution as no adjustment of the kingpin is required and the container box, be it European or U.S. construction, can be simply dropped on to the relevant twist-lock set on the chassis. Thus a single trailer chassis can carry both U.S. and European type containers.
- In a particularly preferred embodiment each set of twist-locks is positioned on the chassis such that upon engagement with the associated container the radius between a pivot axis of the kingpin and a front corner of the container is 2040mm.
- In a further embodiment an associated pair of dual twist-lock assemblies are mounted on the chassis forwardly of the kingpin. Each dual twist-lock assembly includes two juxtaposed twist-locks, namely a front twist-lock associated with the U.S. container and a rear twist-lock associated with the European container, a complementary pair of rear twist-locks associated with each pair of twist-locks in the front dual twist-lock assemblies being mounted at a rear end of the trailer.
- In another embodiment the locking bolts in each front dual twist-lock assembly have axes which are longitudinally spaced-apart on the chassis by a distance of about 151mm and the longitudinal distance between the rear twist-lock bolt axis and a rotational axis of the kingpin is about 700mm.
- In an another embodiment a pair of dual twist-lock assemblies are mounted at a rear end of the trailer, each rear dual twist-lock assembly having a front twist-lock associated with the U.S. container and a rear twist-lock associated with the European container.
- In another embodiment the longitudinal distance between the front twist-locks of the front dual twist-lock assembly at the front end of the trailer and the front twist-locks of the rear dual twist-lock assembly at a rear end of the trailer is 11986mm.
- In a further embodiment a single pair of rear twist-locks are provided at a rear end of the trailer, the spacing between the twist-locks in the dual twist-lock assemblies at the front end of the trailer and the associated rear twist-locks being adjustable.
- In a preferred embodiment the trailer is a two-part telescopically adjustable trailer having a front part slidably mounted on a wheeled rear part, the dual twist-lock assemblies being fixed at a front end of the front trailer part and the rear twist-locks being fixed at a rear end of the rear trailer part.
- Where the trailer has a fixed bed then two pairs of twist-locks are provided at a front end of the chassis and an associated two pairs of twist-locks are mounted at a rear end of the chassis. Thus the container box is engaged with either the foremost pairs of twist-locks at the front end and rear end of the chassis or the rearmost pairs of twist-locks at the front and rear end of the chassis.
- In the case where the trailer is a two part telescopically extendable trailer, two different pairs of front twist-locks are provided on the front trailer part whilst only a single pair of twist-locks is required on the rear trailer part which can be slidably adjustable relative to the front trailer part to position the rear twist-lock pair as required for use with either type of container box.
- In another aspect the invention provides a twist-lock assembly for a trailer for freight containers, the twist-lock assembly comprising two juxtaposed twist-locks, each twist-lock including a container receiving platform and a locking bolt for releasable locking engagement with a complementary receiver on a container, said locking bolt being movable relative to the platform between a raised in-use position extending above the platform and a lowered inoperative position below a container receiving surface of the platform, longitudinal axes of the bolts being spaced-apart by a distance of about 151mm. Preferably an opening is provided in the platform and the bolt is movable through the opening between the raised position and the lowered position.
- Conveniently the double twist-lock assembly may be provided as a modular unit for attachment to a chassis frame. Alternatively two individual twist-locks may be mounted side by side on the chassis frame with the required spacing between the twist-lock locking bolts.
- The invention will be more clearly understood from the following description of some embodiments thereof, given by way of example only, with reference to the accompanying drawings, in which:
- Fig. 1 is an elevational view of an extendable trailer according to the invention, shown in a collapsed position;

-
- Referring to the drawings, and initially to Figs. 5 and 6 there is illustrated a twist-lock assembly according to the invention indicated generally by the reference numeral 1. The twist-lock assembly 1 comprises a pair of juxtaposed twist-
locks locking bolt locking bolt platform 7 and a raised position as shown in Fig. 5 extending upwardly of theplatform 7 for interlocking engagement with a receiver socket on the base of a container box. Eachlocking bolt opening platform 7 for movement between the raised and lowered positions. Ahandle 11, 12 projects outwardly at a lower end of eachlocking bolt locking bolt locking bolt bolts - For a fixed bed trailer four of the twist-lock assemblies 1 are mounted on the trailer chassis, a front pair of the twist-lock assemblies 1 being mounted at a front end of the chassis and a rear pair of the twist-lock assemblies 1 being mounted at a rear end of the chassis. Thus two sets of twist-lock mounts are provided on the chassis, one set for engagement with a European standard 13.6m container box and the other set for engagement with a U.S. standard 45ft container box. The distance X between the rotational axes A of each
locking bolt platforms 7 of the twist-lock assemblies 1 form a bed for reception of the container. - In use, when a container has been dropped on to the fixed trailer chassis it is dropped on to either all the
foremost locking bolts rearmost locking bolts - Referring to Figs. 1 to 4 an extendable trailer according to the invention is shown and indicated generally by the
reference numeral 20, parts similar to those described previously are assigned the same reference numerals. Theextendable trailer 20 is generally similar to the extendable trailer described in my previous patent application, publication No.GB 2 335 891 the contents of which are incorporated herein by reference. Thetrailer 20 essentially comprises afront part 21 slidably mounted on a wheeledrear part 22. Thefront part 21 andrear part 22 essentially comprise a pair of spaced-apart longitudinal beams interconnected by cross members. A number of bolsters project outwardly of the beams to support twist-locks at various spacings on thetrailer 20. The most important of these from the point of view of this invention are afront bolster assembly 24 mounted at a front end of thefront part 21 and arear bolster assembly 25 mounted at a rear end of therear part 22. Therear bolster assembly 25 is as described inGB 2 335 891 and essentially provides a single twist-lock 27 at opposite sides of thetrailer 20 at a rear end of thetrailer 20. - The front bolster
assembly 24 has a pair of laterally extending bolsterarms 28 at an outer end of which are mounted dual twist-lock assemblies 1 of the type previously described. Each twist-lock assembly 1 has a front twist-lock 2 and a rear twist-lock 3 arranged in a tandem configuration as shown in Fig. 4. Akingpin 29 is mounted on an underside of thefront part 21 for engagement with the fifth wheel coupling on a tractor vehicle in conventional fashion. - The mounting of a standard European 13.6 m
container 40 on thetrailer 20 is shown in Figs. 7 and 8. In this case rear twist-lock receivers on an underside of thecontainer 40 are engagable with the rear twist-locks 27 on thetrailer 20 and front twist-lock receivers at a front end of thecontainer 40 are engagable with the rear twist-locks 3 of the dual twist-lock assemblies 1 at a front end of thetrailer 20. It will be noted that the radius R between a pivot axis K of thekingpin 29 and afront corner locks 3 and the rotational axis K of the kingpin is 700mm. - Figs. 9 and 10 show the mounting of a standard U.S. 45
foot container 50 on thetrailer 20. In this case rear twist-lock receiver sockets on an underside of thecontainer 50 again engage with the rear twist-locks 27 on thetrailer 20. However, front twist-lock receivers on thecontainer 50 in this case engage with front twist-locks 2 of the dual twist-lock assemblies 1 mounted at the front end of thetrailer 20. Therear trailer part 22 is slid forwardly relative to thefront trailer part 21 by 151mm prior to mounting thecontainer 50 on thetrailer 20 to accommodate this. It will be noted that in this case also the radius R between the kingpin axis K andfront corners container 50 is 2040mm. - The overhang at the rear end of the
trailer 20 in the case of theU.S. container 50 will be 865mm, whereas in the case of theEuropean container 40 it will be about 714mm. In both cases the distance between the in-use forward twist-locks lock 27 is 11986mm corresponding to fixed spacing between the front and rear twist-lock receivers on an underside of acontainer - The invention is not limited to the embodiments hereinbefore described but may be varied in both construction and detail within the scope of the appended claims.
